Nirav Patel, M.D., from the University of Alabama at Birmingham, and colleagues queried the National Inpatient Sample from 2012 to 2015 for STEMI hospitalizations with the primary payer of Medicaid or private insurance. Outcomes were compared in a propensity score-matched cohort based on demographics, socioeconomic status, clinical comorbidities, STEMI acuity, and hospital characteristics. Data were included for 42,645 and 171,545 STEMI hospitalizations for patients identified as having Medicaid and private insurance, respectively.
